Patent number: 10003097Abstract: A redox flow battery system including a reactive cell with an anode chamber separated from a cathode chamber separated by an ion-permeable membrane is provided. A catholyte reservoir is connected to the cathode chamber by a catholyte fluid circulation circuit. An anolyte reservoir is connected to the anolyte chamber by an anolyte fluid circulation circuit. Nitrogen sparging of reactive oxygen from the catholyte fluid in the catholyte reservoir prevents the formation of a finely divided solid precipitate in the catholyte fluid. Nitrogen may be provided from an external source of nitrogen. Nitrogen may also be provided by the in situ generation of nitrogen from air.Type: GrantFiled: February 17, 2015Date of Patent: June 19, 2018Assignee: VIZN ENERGY SYSTEMS, INCORPORATEDInventors: Paul Abel Trudeau, Jr., Ronald David Brost

Patent number: 7607362Abstract: The present invention relates to a flowmeter for measuring flow rate of a fluid independently of fluid viscosity or density. In at least on embodiment, the flowmeter includes an inlet, an outlet, and a cylindrical chamber. The flowmeter also includes an impeller assembly positioned within a cylindrical chamber for rotation at a variable speed. In at least one embodiment, the flow rate of the fluid is determined when a pressure differential between the fluid in the let and fluid in the outlet becomes substantially zero.Type: GrantFiled: May 21, 2008Date of Patent: October 27, 2009Assignee: Ford Motor CompanyInventor: Ronald David Brost

Patent number: 6656234Abstract: A method is provided for manufacturing a battery 18 having battery electrodes 20 and 22 with a desired porosity, using an electrochemical model 42 and a thermal model 44, that includes determining energy and current requirements for a particular application. Characteristics of the battery 18 in response to said energy and current requirements are determined. The battery characteristics and energy and current requirements are prepared for use in the electrochemical model 42 and the thermal model 44. The porosity of the battery electrodes is determined by solving equations within the electrochemical model 42 and the thermal model 44. Porosity of the battery electrodes is varied until voltage potential across the battery varies by less then a predetermined tolerance factor for an operating range state of charge. A paste mixture is created in response to the desired battery electrode porosity. The paste mixture is applied to a grid followed by curing of the grid and paste.Type: GrantFiled: September 26, 2001Date of Patent: December 2, 2003Assignee: Ford Global Technologies, LLCInventors: Derek Richard Dexter, Ronald David Brost

Patent number: 6422027Abstract: A battery cooling system 10 for use with a vehicle 14 including several batteries or battery modules 16-38 which provide power to the vehicle 12. The system 10 includes a refrigerant gas channeling or conduit system which is effective to store, compress, expand and circulate refrigerant gas through the battery pack 12 and the system 10. A first “high pressure” conduit system, having several tubes or conduits that are disposed throughout the vehicle 14, is used to selectively carry and transport pressurized or compressed refrigerant gas to the battery pack 12 and includes a pump 42, a heat exchanger 44, expansion valves 46-52, and conduits 54, 56, 58, 60 and 62. A second “low pressure” conduit system is used to circulate the “expanded” or decompressed refrigerant gas throughout the battery pack 12 and to return the refrigerant gas to pump 42 for recompression.Type: GrantFiled: May 3, 2001Date of Patent: July 23, 2002Assignee: Ford Global Tech., Inc.Inventors: Calvin Edward Coates, Jr., Ronald David Brost
